What does the “D2” in MY[]N-D2 General-purpose Relays indicate?


It indicates that the relays have a built-in diode to suppress surges generated from the DC coil of relays.

When transistors are used to operate relays, any effects on the transistor caused by the surge, such as deterioration and breakdown, will be eliminated.


1.Make sure that the polarity is correct.

2.The reset time will be longer, but it will still be within 20 ms.

3.Diode characteristics:
Reverse breakdown voltage: 1,000 V
Forward current: 1 A
